a) Enhanced Surface Area for Heavy Loads K3 media features a more complex internal structure, providing a larger protected surface area compared to K1. This allows for a higher concentration of biomass, making it highly effective for treating high-strength industrial wastewater, such as papermaking and textile (printing/dyeing) wastewater.

b) Ideal for Aquaculture (RAS) Due to its excellent nitrification capabilities, it is widely utilized in Recirculating Aquaculture Systems (RAS) to maintain safe ammonia levels for aquatic life.
